6:41pm] rumpler: danieldaniel: I think your explanation of split-key addresses was a little off. You say that you only send them your public key and they don't have the private, but you don't mention that this is a totally unrelated pub/privkey from Bitcoin addresses.
Quoted from IRC.
EDIT: Although, I don't think he's right. See
https://en.bitcoin.it/wiki/Split-key_vanity_address. It says that the priv keys are merged.
